ULPHOLSTERY-SPRING CONSTRUCTION.

1 '0 all whom it may concern Be it known that I, LEONARD A. Youxo, a citizen of the United States, residing at Detroit,'in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Upholstery-Spring Constructions, of which the following is a specification. i

In the construction of spring seats for vehicles and furniture, articularly those of the type wherein the cus ions are removable,

it is desirable to provide a base frame that possesses some rigidity together with lightness, and that affords an adequate method of securing the members of the frame and the springs employed togetheryyith members of the parts, and at the same time securely holds the depending upholstery cover or apron in place without the necessity of tacking strips or like means.

Y This invention relates to a spring seat strul'fture and particularly to the base frame thereof that is so designed as to possess the rigidity desired whereby the cushion may be removed bodily from the support without permanent deformation, that is readily manufactured because it is easily assembled V and that is also formed So that the apron of upholstery is quickly secured without the necessity-of extraneous parts.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

, In the drawings:

Figure 1 is a plan view, partially broken away and in section, of a spring structure that embodies features of the invention;

Fig. 2 is a view in transverse section therethrough;

Fig. 3 IS a view in detall showing one form of the base rim strip and upholstery apron Fig. 5 is an enlarged view in detail of one modification of the strip.

' Refer-ring to the drawings, a base frame is formed of a sheet metal strip folded inter mediate .its margins to form a hollow rib 1,

the upper marginal portion 2 being reverted into overlying relation to the adjacent por tion of the bead or rib l and the lower mar-- ginal portion 4 being likewise returned in underlying relation t the underside 5 of Specification of Letters .Patent.

the head 1. Vhile the parts 2 and 4: are herein indicated in spaced relation to the walls 3 and 5, they may be flattened against the same, although the spaced relation of the parts herein indicated is preferred.

The inarginal portion of the member a is turned as indicated at 6 and; similarly; the outer portion of the part 2 is down turned as indicated at 7.

The strip 1 may be made continuous around the frame or it may be built of such conveniently sized sections as desired. Cross supporting Strips or transverse members 8 have their end portions inserted in the groove formed by the bead l wherethey are secured by spot welding or suitable compressing of the strip. I These cross members may be of any preferred form and suitable design and are herein shown as of U-section with the flanges disposed in horizontal position, whereby the base turns 9 of springs 10 may be inserted, therein and clenched in position by pinching the-'embracing flanges indicated at 11. That strip 8 which is adjacent the end portion of the frame, is so disposed that the groove of the strip cooperates with the groove of the adjacent portion 12 as holding means of the base turns of the interposed body springs. The intermediate strips 8 are arranged in pairs with their flanges turned toward each other and body springs are inserted between the flanges of each pair. In order to further stay the springs. the latter may be connected by shortsections 13 of U-strips that grip intermediate turns 14'0f the springs, or other stay means may be used, and clips 15 are likewise employed if desired to hold the upper coils of the body springs in place.

The usual rim frame 16 is carried by the body springs if desired. Upholstery filling 17 is placed on the springs with a customary covering 18; The depending marginal portions 19 of the covering form the usual aprons.

The lower margins of the aprons which are provided with a welt edge 20 or are merely hemmed or otherwise reinforced, are tucked between the portions 6 and 7 of the strip-and secured there by the natural interlocking which results from the relation of the spacing member (3 and 7. That is. ill). normal distance between the outer margin of the outer portion 7 and the adjacent part of the member 6, isless than the space between the inner nor-tions of these flanges, and when her 1' the welt or hemmed edge is tucked therein, the spring edges of these maintain the same in position. Or if preferred, the outer menimay be clenched down upon the upholstery as by an air hammer with suitably proportioned jaws for accomplishing this purpose or by hand or the like.

in the enlarged detail of Fig. 4 a rim strip is shown having a hollow bead 20 from which spring rounded flanges 21 and 22, the outer edges 23 and 24 of which overlap and permit the tucking of the fabric as indicated at into position in the wider space'of the body of the strip itself. The walls of the flanges of this construction are arched and this increases the strength of the rib against longitudinal fiexion.

In Fig. 5, the strip shown in Fig. 3 is *placed in reversed posit-ion with the lower rib 26 overlying the depending part of the upper ii) 2?, the upholstery apron margin 28 being inserted in the space between the ribs and being protected against chafing on the spring support by the position of the part 2-6. f

As a result of this invention, a spring seat obtained that is extremely rigid, while at the same time the base frame afi'ords ready means for connection with the springs and the other parts of the structure without the necessity of clips or like holding devices and upholstery is readily applied in such a man nor that a continuous, unbroken grip ismaintained alon its margin without the neces sity of tacking'or the like. I

Gbvioasly', changes in the details of con-' struction may be had without departing from the spirit of my invention, and I do not care to limit myself to any particular form or arrangement of parts.

What I claim is:

1. In upholstery spring construction, a

frame having a sheet metal rim strip folded intermediate its margins into ahollow rib, the n'iargmal portions being reverted and extending beyond the body of the rib with the resultant flanges inturned slightly in spaced;

relation.

2. .ln upholstery spring construction,- a base frame including a sheet metal rim strip folded intermediate its margins into a hollow rib opening inwardly, the marginal portions being reverted to provide flanges extending outwardly beyond the body of the rib, the outer portions of the flanges being turned toward each other and slightly separated;

3. In u 'iholstcry spring construction, a base. a rim in the base consistiug'of a sheet metal strip folded intermediate its margins into an inwardly hollow rib, the marginal portions bring reverted to,provideoutwardly extending flanges the outer portions of which are turned toward each other, body springs reverted and formed into flanges extendin groove of the rim, body springs on the supports and upholstery thereon including an apron, the margins of which are held between the flanges of the rim.

5.In upholstery spring construction, a

base-frame, a sheet metal rim strip in the frame formed between its margins to provide an inner longitudinal groove with the marginal portions of the strip extending outwardly in inturned spaced relation, the

frame having transverse members secured at the extremities in the groove of the rim, springs on the frame, and upholstery on the springs including a covering, the margin of which is inserted between t e rim flanges.

6. In upholstery spring construction, a

base frame rim strip formed into a hollowrib intermediate its margins providing an inner groove, the marginal portions being I) 1' beyond the body of the rib and lying in inturned spaced relation, U-section transverse stripssecured at their extremities in the hollow rib of the rim, bodysprings, the base turns of which are inserted in the grooves of the transverse and rim strips and upholstery on the springs having :1 depending apron which is secured along its margins by the cooperating flanges of the rim strip.

7. In upholstery spring construction, a

base frame consisting of a rim strip having a longitudinal [groove on its inner face and outwardly. extending mturned flanges, spring supporting members spa nnmg the frame and resting in the groove of the rim, body springs mounted on the frame, stay members connecting intermediate coils of the body springs, an upper rimframe supported by the springs and upholstery having an apron the margin of which is secured in position by the cooperating flanges of the base frame rim.

8. In upholstery spring construction, a. strip forming. a. member of a base frame consistmg of a sheet metal bar l'olded to form awhollow rib between the margins of the strip, the substantially parallel sides of the rib being reverted to form outwardly extending flanges in parallel, spaced relation to the adjacent faces of the rib, the marginal portions of the flanges lying insubstantial] v overlapped and spaced relation.

In testimony whereof I allix my siguatmr.
